The Sydney Sixers entered the season as "hot favourites", but they lost five consecutive games in the back-half of the tournament and missed out on qualifying for finals for the first time after captain Ellyse Perry sustained a shoulder injury. Defending champions Brisbane Heat finished the regular season on top of the ladder, earning the right to host all three playoff matches at Allan Border Field.
The Heat retained their title on 8 December 2019 when they defeated first-time finalist Adelaide Strikers, featuring Player of the Tournament Sophie Devine, by six wickets in the championship decider. Beth Mooney was named Player of the Final for the second consecutive season.
